The AT-4 is a man-portable, disposable, single-use anti-tank
weapon, developed by FFV (now SAAB-Bofors) in Sweden. The name of the weapon is
a play on its 84 mm bore (AT-4 is pronounced as "Eighty-Four"), as well an
indication of its role (AT for "anti-tank"). It was and remains one of the
world's premier expendable infantry anti-tank weapons. It is also distinct from
most other weapons in its class, being a recoilless gun rather than a rocket
launcher, though many sources still mistakenly identify it as the latter. The
AT-4 is also often assumed to simply be a disposable version of the Carl Gustav
M2, but the only major attribute their ammunition shares is the same bore.

All AT4 weapons are single shot and fully
disposable. You simply aim, fire, destroy the target and discard the empty tube.
Furthermore, the AT4 family has proven itself to be a highly reliable, robust
and durable weapon system that has been extensively proven in combat. Its key
characteristics include high target effect and hit probability – creating a high
target kill probability for each fired weapon.

The
AT4 is an 84-mm unguided, portable, single-shot recoilless smoothbore weapon
built in Sweden by Saab Bofors Dynamics. Saab has had
considerable sales success with the AT4, making it one of the most common light
ant-tank weapons in the world.

The AT4 is intended to give
infantry units a means to destroy or disable armoured
vehicles and fortifications,although it is generally ineffective against
current modern main battle tanks (MBT).The launcher
and projectile are manufactured pre-packed and issued
as a single unit of ammunition.

The AT-4's gun tube is long and cylindrical, with numerous external fixtures.
The muzzle is surrounded by a thick composite bracket, which in turn is
enveloped by an octagonal shock absorber; the venturi is flared, conical, and
has an octagonal shock absorber rim as well, though its visibly broader than the
muzzle. Numerous brackets are wrapped around the tube, making quick
identification by counting them relatively pointless. The shoulder pad on the
aft underside has a broad salient shape, and includes a folding wire-frame
shoulder rest with a short canvas strap; when extended, the shoulder rest
takes-on a delta shape. A long tube covered by a conformal housing (which
contains a cable used to fire the weapon) runs from the trigger mechanism to the
breech along the top of the tube. The front and rear sights are located on the
forward upper right side of the tube, underneath rectangular protective covers
which can be slid-away when the sights needs to be raised. A rectangular
foregrip is located just behind the muzzle on the underside of the weapon, and
is folded against the tube when not in use (some AT-4s were produced without a
foregrip). The firing mechanism, safety catch, and cocking lever are on top of
the tube in its midsection, just behind the rear sight cover. The AT-4 is
usually fitted with a sling, the swivels for which are located on the lower left
side between the sight covers, and on the very bottom of the tube just in front
of the venturi. Various stencilings and instructional decals are plastered onto
the tube. AT-4s may be painted in different colors or camouflage patterns, but
are usually solid olive drab in color.
The construction of the AT-4's gun tube is extremely similar to that of most
modern disposable anti-tank rocket launchers, but is still able to cope with the
overpressure of an 84 mm recoilless round. The tube consists of reinforced
fiberglass, with numerous sheet steel and composite brackets. Unlike the Miniman,
the bore liner is not metallic, although the venturi is made of aluminum. The
shock absorbers on the AT-4 are made of a hard foam rubber material. The sights,
trigger mechanisms, and shoulder rest frame are made of steel, while the sight
covers, foregrip, and numerous other fixtures are made of plastic. The
projectile itself has an aluminum shell, and the fins are probably made of
aluminum as well. The AT-4 is rated for operating temperatures of −40 to +60 °C.

The iron sights consist of a front post and a rear peephole, with the range
adjustable for 100 m to 500 m, in 50 m increments. Two different peepholes are
available for the AT-4; a 2 mm hole for use in broad daylight, and a 7 mm
peephole for use at night and in order low-visibility situations. Interestingly
similar set of sights are also used on the M141 BDM anti-structure rocket
launcher, probably due to a similar range and trajectory. A variety of optics
may also be fitted to the AT-4 by clipping them on, to include night vision
optics, infrared optics, and laser aiming devices.
The main body of the projectile is shaped like a generic artillery shell,
with a cylindrical body, a finely-tapered conical nose, and a boattail. It has a
diameter of 84 mm, a length of 462 mm, and a fin span of 290 mm. The trailing
body consists of a metal shaft, enveloped by a spring-loaded assembly containing
6 stabilizer fins that spring into a hexagonal pattern when the projectile
leaves the tube. The main body of the projectile is marked with a yellow band,
for easy identification of UXO, should the projectile fail to launch and/or
detonate properly. The projectile is fired down a smooth bore, and is stabilized
solely by drag via its fins when in flight, as it does not rotate. Although the
AT-4 is frequently referred-to as a "rocket launcher", the projectile does not
contain a rocket motor.

The AT-4 projectile weighs 1.81 kg, and contains 453 g of Octol
that force a thin copper charge liner into a jet-like penetrator upon
detonation. This charge will penetrate up to 400 mm of RHAe at a 0-degree
obliquity, but there is more to the lethality of the warhead than just its
penetration. The AT-4 was the first anti-tank munition especially designed to
employ enhanced lethality against armored vehicles, through what the
manufacturer has termed "Beyond Armor Effects". Using a number of special
attributes built into the warhead, the damage caused to the interior of a
penetrated armored vehicle and its occupants are dramatically increased,
resulting in a significantly greater probability of disabling an armored
vehicle. These effects include an instantaneous overpressure of 1 bar above
normal (twice the ambient air pressure of the Earth's atmosphere at sea level),
greatly increased back-spalling and penetrator spatter, a flash of light over
100 times stronger than sunlight, greatly increased smoke from combustion of the
warhead and armor during penetration, and more intense heat than that of a
generic shaped charge of similar penetration. Exactly what components of the
AT-4's warhead create the Beyond Armor Effects are still highly classified
(though observers have noted that it probably has something to do with the
charge liner's unusual trumpet-like shape, a focus ring around the front of the
liner, or an additional layer of a special aluminum-based alloy bonded to the
back of the liner), but as video footage and photographs of AT-4s hitting
armored vehicles graphically demonstrate, they are not a marketing
overstatement.

The AT-4 may be fired from a
standing, sitting, kneeling, or prone position, though prone firings are
typically forbidden during training. When firing from a prone position, the user
must lie at a 45-degree angle off the axis of fire, as being exposed to the
backblast at the venturi will result in severe injuries.
To fire the AT-4, the user must first remove the safety pin at the rear of
the launch tube, ensure no personnel are in the backblast area, and shoulder the
weapon. If the iron sights are to be used, the user must slide the cover for the
front sight rearward, slide the cover for the rear sight forward, and flip-up
the sights. The cocking lever must then be flipped moved forward, upward, then
to the right, then take aim at the target. When the target is in the user's
sights, the safety lever must then be held down, and the trigger button
pressed-down by the user's thumb; if the cocking lever is not set to the armed
position and the safety lever held-down with the trigger is pressed, the trigger
will not engage and fire the weapon. The user must also *squeeze* the trigger
until it "breaks" (like the trigger on a typical rifle) rather than simply
jabbing it, as doing the latter could throw-off the aimpoint. The weapon will
then fire, and the tube is discarded; it isn't designed to withstand the
stresses of multiple firings, and thus cannot be reloaded.
